Said strand guide installation (100) comprises a segmented frame with at least one cross member (112-1, 112+1) which are arranged in parallel to each other and stationarily in the direction of the width of the metal strip (200). A guide element (112-0) is received in parallel to the cross member and perpendicular to the plane of the metal strip so as to be vertically displaceable or oscillatable. According to the invention, the guide element (112-0) and the measuring roller (120) can be received so as to be vertically displaceable and supported on the stationary cross member (112-1, 112+1) by means of guide bars (130) in an especially simple manner.

Description

Strangführungseinrichtung zum Führen eines MetallbandesStrand guiding device for guiding a metal strip
Die Erfindung betrifft eine Strangführungseinrichtung zum Führen eines Metallbandes, insbesondere einer Bramme.The invention relates to a strand guiding device for guiding a metal strip, in particular a slab.
Eine derartige Strangführungseinrichtung ist zum Beispiel aus der europäischen Patentanmeldung EP 1 525 931 A1 bekannt. Die dort offenbarte Strangführungseinrichtung umfasst einen Segmentrahmen mit einer Mehrzahl von quer zur Transportrichtung angeordneten Traversen. Die Traversen sind zueinander parallel ausgerichtet und in dem Segmentrahmen ortsfest angeordnet. Zwischen zweien dieser Traversen ist ein erstes Führungselement mit einer Messerolle angeordnet. Das erste Führungselement mit der Messrolle ist in einem zweiten Führungselement vertikal gegenüber der Ebene des zu führenden Metallbandes verschiebbar gelagert. Die Lagerung des ersten Führungselementes in dem zweiten Führungselement erfolgt sehr aufwändig mithilfe von Druckfedern und Seilen.Such a strand guiding device is known, for example, from the European patent application EP 1 525 931 A1. The strand guide device disclosed therein comprises a segment frame with a plurality of cross members arranged transversely to the transport direction. The trusses are aligned parallel to each other and arranged stationary in the segment frame. Between two of these trusses, a first guide element is arranged with a knife roller. The first guide element with the measuring roller is mounted in a second guide element vertically displaceable relative to the plane of the metal strip to be guided. The storage of the first guide element in the second guide element is very complicated by means of compression springs and ropes.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, eine bekannte Strangführungseinrichtung dahingehend weiterzubilden, dass die Lagerung des vertikal verschiebbaren Führungselementes mit der Messrolle vereinfacht ausgebildet ist.Based on this prior art, the invention is based on the object to further develop a known strand guiding device to the effect that the storage of the vertically displaceable guide element is formed simplified with the measuring roller.
Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Demnach ist das Führungselement mit Hilfe von Lenkern an der ortsfesten Tra- verse vertikal verschiebbar gelagert und abgestützt.This object is solved by the subject matter of patent claim 1. Accordingly, the guide element by means of links on the stationary Traverse is mounted vertically displaceable and supported.
Der Begriff „ortsfest" ist bei der vorliegenden Beschreibung im Sinne von ruhend gegenüber dem vertikal verschiebbaren bzw. oszillierbaren Führungselement mit der Messrolle und ruhend gegenüber dem transportierten Metallband zu verstehen. Die beanspruchte Verwendung der Lenker zur Lagerung des Führungselementes mit der Messrolle gestattet zwar eine gewünschte Bewegung des Führungselementes vertikal zur Ebene des Metallbandes, aber eine Bewegung des Führungselementes in Transportrichtung des Metallbandes und in Breitenrichtung des Metallbandes wird wirkungsvoll unterbunden. Dies hat den Vorteil, dass das im Stand der Technik erforderliche zweite Führungselement sowie die dort zur Stabilisierung des ersten Führungselementes benötigten Druckfedem, Gleitsteine und Seile eingespart werden können. Insbesondere durch den Wegfall des aus dem Stand der Technik bekannten zweiten Führungselementes kann das erfindungsgemäße Führungselement mit der Messerolle nun auch bei Strangführungseinrichtungen eingesetzt werden, bei denen die Traversen relativ eng zueinander beabstandet angeordnet sind, d.h. bei engen Einbauräumen.The term "stationary" is to be understood in the present description in the sense of resting against the vertically displaceable or oscillatable guide element with the measuring roller and resting against the transported metal strip. Although the claimed use of the links for supporting the guide element with the measuring roller permits a desired movement of the guide element vertically to the plane of the metal strip, but a movement of the guide element in the transport direction of the metal strip and in the width direction of the metal strip is effectively prevented. This has the advantage that the second guide element required in the prior art as well as the pressure springs, sliding blocks and cables required there for stabilizing the first guide element can be saved. In particular, by eliminating the second guide element known from the prior art, the guide element according to the invention with the knife roller can now also be used in strand guiding devices, in which the traverses are arranged relatively close to each other, ie in tight installation spaces.
Die Traverse(n), sei(en) sie vorgelagert und/oder nachgelagert, an denen die Lenker zur Halterung des Führungselementes mit Messrolle befestigt ist/sind, kann /können zu dem Führungselement mit der Messrolle unmittelbar benachbart angeordnet sein. Alternativ können zwischen der vorgelagerten Traverse und dem Führungselement mit der Messrolle und/oder zwischen der nachgelagerten Traverse und dem Führungselement mit der Messrolle weitere Traversen, vorzugsweise mit Segmentrollen, angeordnet sein. Die weiteren bzw. zwi- schenliegenden Traversen werden dann von den Lenkern vorzugsweise berührungslos überbrückt.The traverse (s), be it (s) upstream and / or downstream, where the handlebar is attached to support the guide element with measuring roller / can be arranged to the guide element with the measuring roller immediately adjacent. Alternatively, between the upstream cross member and the guide element with the measuring roller and / or between the downstream traverse and the guide element with the measuring roller, further traverses, preferably with segmented rollers, may be arranged. The further or intermediate trusses are then preferably bridged by the links without contact.
Die Messrolle kann antriebslos oder mithilfe einer Antriebseinrichtung antreibbar ausgebildet sein.The measuring roller can be driveless or drivable by means of a drive device.
Weitere vorteilhafte Ausgestaltungen der Strangführungseinrichtung, insbesondere der Lenker, der Stelleinrichtung zum Anstellen des Führungselementes mit der Messrolle gegen das Metallband und der Druck- und/oder Wegmesseinrichtung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the strand guide device, in particular the link, the adjusting device for hiring the guide element with the measuring roller against the metal strip and the pressure and / or displacement measuring device are the subject of the dependent claims.

In all figures, like elements are designated by like reference numerals.
Figur 1 zeigt eine Strangführungseinrichtung 100 zum Führen eines Metallbandes 200, insbesondere einer Bramme. Die Bramme 200 wird dabei in einer Transportrichtung R transportiert. Die Strangführungseinrichtung 100 umfasst einen Segmentrahmen (hier nicht gezeigt) mit mindestens einer in Transport- richtung R vorgelagerten Traverse 112 -1 und einer nachgelagerten Traverse 112 + 2 (siehe Figur 2), die parallel zueinander und quer zu der Transportrichtung R ortsfest angeordnet sind. Zwischen der vorgelagerten und der nachgelagerten Traverse 112 -1 , 112 +1 und parallel zu diesen ist ein erstes Führungselement 120-0 gelagert. Das erste Führungselement ist quer zur Ebene des Metallbandes vertikal verschiebbar gelagert. An dem ersten Führungselement 112 -0 ist eine Messrolle 120 zum Kontaktieren des Metallbandes 200 drehbar gelagert. Das erste Führungselement 112 -0 ist mithilfe von Lenkern 130 -1 , 130 -2 an vorzugsweise der Oberkante O der vorgelagerten ortsfesten Traverse 112 -1 und mithilfe von Lenkern 130 -3, 130 -4 an vorzugsweise der Unterkante U der nachgelagerten ortsfesten Traverse 112 +1 vertikal verschiebbar beziehungsweise oszillierbar gelagert. Bei dem in Figur 1 gezeigten ersten Ausführungsbeispiel sind die vorgelagerte Traverse 112 -1 und die nachgelagerte Traverse 112 +1 (strichpunktiert) dem Führungselement 112-0 unmittelbar benachbart angeordnet.FIG. 1 shows a strand guiding device 100 for guiding a metal strip 200, in particular a slab. The slab 200 is transported in a transport direction R. The strand guiding device 100 comprises a segment frame (not shown here) with at least one traverse 112-1 arranged upstream in the transport direction R and a downstream traverse 112 +2 (see FIG. 2) which are arranged in a stationary manner parallel to one another and transversely to the transport direction R. Between the upstream and the downstream traverse 112 -1, 112 +1 and parallel to these, a first guide element 120-0 is mounted. The first guide element is mounted vertically displaceable transversely to the plane of the metal strip. On the first guide element 112 -0, a measuring roller 120 for supporting the metal strip 200 is rotatably mounted. The first guide element 112 -0 is by means of links 130 -1, 130 -2 preferably at the upper edge O of the upstream stationary cross member 112 -1 and by means of links 130 -3, 130 -4 preferably at the lower edge U of the downstream stationary crossbar 112th +1 vertically displaceable or oscillatory stored. In the first embodiment shown in Figure 1, the upstream traverse 112 -1 and the downstream traverse 112 +1 (dash-dotted lines) the guide element 112-0 immediately adjacent.
In Figur 1 ist weiterhin eine Stelleinrichtung zum Anstellen des Führungselementes mit der Messrolle 120 gegen das Metallband 200 gezeigt. Die Stelleinrichtung ist vorzugsweise in Form von zwei positionsgesteuerten Hydraulikzylindern 150a, 150b ausgebildet, welche auf Höhe der Ränder des Metallbandes an dem Führungselement 120 -0 angreifen. Alternativ könnte die Stelleinrich- tung auch nur einen positionsgesteuerten Hydraulikzylinder umfassen, welcher dann vorzugsweise so angeordnet ist, dass er in der Mitte des Führungselementes angreift.FIG. 1 also shows an adjusting device for adjusting the guide element with the measuring roller 120 against the metal strip 200. The adjusting device is preferably in the form of two position-controlled hydraulic cylinders 150a, 150b, which engage at the level of the edges of the metal strip on the guide element 120-0. Alternatively, the actuating device could also comprise only one position-controlled hydraulic cylinder, which is then preferably arranged so that it engages in the middle of the guide element.
Weiterhin umfasst die Strangführungseinrichtung bzw. die Stahleinrichtung eine Druckmesseinrichtung 160a, 160b zum Erfassen einer durch das Metallband 200, ggf. aufgrund von dessen ferrostatischem Druck, auf die Messrolle 120 ausgeübten Krafteinwirkung. Vorzugsweise ist die Druckmesseinrichtung ausgebildet zum Erfassen der Krafteinwirkung auf die Messrolle in Form des Druckes in den Hydraulikzylinder 150a, 150b der Stelleinrichtung.Furthermore, the strand guiding device or the steel device comprises a pressure measuring device 160a, 160b for detecting a force exerted on the measuring roller 120 by the metal strip 200, possibly due to its ferrostatic pressure. Preferably, the pressure measuring device is designed to detect the action of force on the measuring roller in the form of the pressure in the hydraulic cylinder 150a, 150b of the actuating device.
Schließlich umfasst die Stelleinrichtung weiterhin eine Wegmesseinrichtung (162a, 162b) zum Erfassen der jeweils von dem Führungselement bzw. der Messrolle 120 gegenüber einem Bezugspunkt, z.B. dem Segmentrahmen, zurückgelegten Wegstrecke. Vorzugsweise ist die Wegmesseinrichtung in den Hydrualikzylindern integriert zum Erfassen der Wegstrecke in Form des von den Zylindern zurückgelegten Weges.Finally, the adjusting device further comprises a displacement measuring device (162a, 162b) for detecting the respective of the guide element and the measuring roller 120 with respect to a reference point, e.g. the segment frame, traveled distance. Preferably, the path measuring device is integrated in the Hydrualikzylindern for detecting the distance in the form of the distance traveled by the cylinders way.
Sowohl die von der Druckmesseinrichtung erfassten Druck- bzw. Kraftwerte wie auch die von der Wegmesseinrichtung erfassten Wegstrecken werden vorteil- harter Weise von einer Auswerteeinrichtung ausgewertet, um eine Aussage ü- ber die Konsistenz des Metallbandes, beispielsweise einer Bramme, zu erhalten, insbesondere im Hinblick auf den Grad von dessen Durcherstarrung.Both the pressure and force values detected by the pressure-measuring device and the distances covered by the displacement-measuring device are advantageously evaluated by an evaluation device in order to obtain a conclusion. On the consistency of the metal strip, such as a slab to obtain, in particular with regard to the degree of its solidification.
Die soeben beschriebenen Mess- und Auswerteeinrichtungen sind zwar nur in Fig. 1 für das erste Ausführungsbeispiel gezeigt; sie können aber bei allen wei- ten Ausführungsbeispielen gleichermaßen vorgesehen werden.Although the measuring and evaluation devices just described are shown only in FIG. 1 for the first embodiment; However, they can be provided equally in all the other embodiments.
Figur 2 zeigt ein zweites Ausführungsbeispiel für die erfindungsgemäße Strangführungseinrichtung in einer Querschnittsansicht. Das zweite Ausführungsbeispiel unterscheidet sich von dem ersten Ausführungsbeispiel dadurch, dass die Lenker 130 -1 , 130 -3 zum Stützen und Lagern des Führungselementes 112 -0 nicht an den unmittelbar zu dem Führungselement 120-0 benachbarten Traversen 120 -1 , 120 +1 , sondern jeweils an den übernächsten Traversen 112 -2, 112 +2 befestigt sind. Idealerweise sind die Lenker 130-3, 130-4 bei der benachbarten Traverse 120 +1 zwischen deren Unterkante U und deren Segment- rollen 120+1 hindurchgeführt. Gleichzeitig ist die benachbarte, in Transportrichtung R vorgelagerte Traverse 120 -1 durch die Lenker 130 -1 , 130 -2 berührungslos überbrückt. Durch das Überbrücken der jeweils unmittelbar benachbarten Traversen bei dem zweiten Ausführungsbeispiel können die Lenker 130 länger ausgebildet sein als bei dem ersten Ausführungsbeispiel; dies hat den Vorteil, dass das Führungselement 120-0 zusammen mit der Messrolle 120 größere Oszillationshübe ausführen kann als bei dem ersten Ausführungsbeispiel.FIG. 2 shows a second exemplary embodiment of the strand guiding device according to the invention in a cross-sectional view. The second embodiment differs from the first embodiment in that the links 130-1, 130-3 for supporting and supporting the guide element 112-0 are not connected to the cross members 120-1, 120 + 1 immediately adjacent to the guide element 120-0, but are each attached to the next traverses 112 -2, 112 +2. Ideally, the handlebars 130-3, 130-4 are guided in the adjacent traverse 120 +1 between the lower edge U and the segment rollers 120 + 1. At the same time, the adjacent, upstream in the transport direction R Traverse 120 -1 is bridged by the handlebars 130 -1, 130 -2 contactless. By bridging the immediately adjacent trusses in the second embodiment, the links 130 may be formed longer than in the first embodiment; This has the advantage that the guide element 120-0 together with the measuring roller 120 can perform larger oscillation strokes than in the first embodiment.
Figur 3 zeigt ein drittes Ausführungsbeispiel für die erfindungsgemäße Strang- führungseinrichtung in einer Querschnittsansicht. Das dritte Ausführungsbeispiel unterscheidet sich von dem ersten und zweiten Ausführungsbeispiel dadurch, dass die Lenker 130 -1 , 130 -3 das Führungselement 112 -0 lediglich gegenüber einer unmittelbar oder nicht-unmittelbar benachbarten Traverse stützen und lagern. Die Traverse kann gegenüber dem Führungselement 112-0 in Transportrichtung R vor- oder nachgelagert sein. Bei allen Ausführungsbeispielen können die Lenker (130) als starre Verbindungselemente mit beidseitig angeordneten Gelenken oder als biegeelastische Verbindungselemente, beispielsweise als Blattfedern, ausgebildet sein. FIG. 3 shows a third exemplary embodiment of the strand guiding device according to the invention in a cross-sectional view. The third embodiment differs from the first and second embodiments in that the handlebars 130 -1, 130 -3 support and support the guide element 112-0 only relative to a directly or indirectly adjacent crossbeam. The traverse may be upstream or downstream of the guide element 112-0 in the transport direction R. In all embodiments, the links (130) may be designed as rigid connecting elements with joints arranged on both sides or as flexible elastic connecting elements, for example as leaf springs.
